If you're in town, throw your bike on the free gondola and then ride through the plaza, past the peaks hotel, and start the ride at a gravel pullout on the north side of the road. If the on-mountain trails are open, getting off at the top of the gondola is a great way to get to Jurassic and add some meat to the ride. Prospect
or the Village Trail
link up with this ride very nicely on the front end.
Starting from Country Club Dr, ride Jurassic through the forest until you reach a paved road. Head downhill for a couple of hundred feet then ride up for a minute until you can rejoin the trail on the right hand side of the road.
The trail is really fast, smooth, and fun, and goes through very nice forest. There are often beginner bikers in the area, so be courteous.
The next road you'll reach is hw 145 and a Right hand turn will bring you to the upper and lower valley trails back to town. Some other options are to ride the paved road all the way back to town, link up with some trails on the north side of the canyon, or head left on 145 to ride T35 to Illium. or just stop off in Lawson hill for a beer at the TBC taproom.
